## Discrepancy

AIRCRAFT WAS GROUNDED: FLIGHT CREW REPORTED THAT AT CRUISE, NOTICED THAT ON THE OVERHEAD PANEL, ENGINE 1 FIRE AGENT 2 INDICATES DISCHARGE. MAINTENANCE FOUND PRESSURE SWITCH THREADS ON THE FIRE BOTTLE DAMAGED PREVENTING THE CANNON PLUG FROM MAKING FULL CONTACT AND BEING SECURED. MAINTENANCE REPLACED THE RIGHT HAND AFT FIRE BOTTLE FOR #1 ENGINE PER AMM 26-21-41. A SATISFACTORY OPERATIONAL CHECK WAS ACCOMPLISHED AND THE LIGHT EXTINGUISHED.
